Value Collection B52001616 Hex Lock Nut 1-1/2-12 Unf

Product Description

The VALUE COLLECTION B52001616 is a nylon insert hex lock nut designed to resist loosening caused by vibration and torque in threaded assemblies. Manufactured from Grade B steel with a zinc-plated finish for corrosion resistance, this nut features a 1-1/2-12 UNF right-hand thread and a captive nylon insert that grips the mating fastener and maintains clamping force without the need for additional locking hardware. It measures 1-39/64 inches in height with a width across flats of 2-3/16 inches. This nut is a standard inch-system fastener suited for mechanical, industrial, and structural assemblies where vibration resistance is required.

This hex lock nut is used across a wide range of industrial and commercial applications including machinery, structural frameworks, equipment mounting, and general mechanical assemblies. It is appropriate wherever a 1-1/2-12 UNF thread engagement is required and where joint integrity must be maintained under dynamic loads or continuous vibration. Tradespeople, millwrights, pipefitters, and general contractors working with threaded assemblies in this size range will find it compatible with standard 1-1/2-12 UNF bolts and studs.

Key Features

• Nylon insert locking style resists loosening from vibration without damaging mating threads
• Grade B steel construction provides reliable strength for standard mechanical fastening applications
• Zinc-plated finish offers corrosion resistance for general indoor and light-exposure environments
• 1-1/2-12 UNF right-hand thread conforms to inch-system fastener standards
• Width across flats of 2-3/16 inches accepts standard hex wrenches and sockets
• Does not require secondary locking hardware such as lock washers or thread-locking compounds

Compatibility

Designed for use with 1-1/2-12 UNF right-hand threaded bolts and studs conforming to inch-system fastener standards.

Installation Notes

Installation should be performed by qualified tradespeople using an appropriately sized hex socket or wrench matched to the 2-3/16 inch across-flats dimension. Nylon insert lock nuts are single-use by design — once the insert has been deformed by engagement, replace the nut rather than reusing it. Ensure the mating bolt threads are clean and free of damage before installation to avoid compromising the nylon insert.
